Letters Patent No. 111,035, dated January 17,1871.

IMPROVEMENT lNFEED-CUTTERS.

The Schedule referred to in these Letters Patent and making part; of thesame.

To all whom it may concern Be it knowir that I, JOSEPH H. BRADLEY, ofHillsborough, in the county of Highland and State of Ohio, have inventedanew and improved Feed- Figure 3, a detached elevation of the disk I,with its adjustable crank-pin and the slotted oscillating bar' li; and

Figure 4 is a perspective view of the ily-wheel, having'the cutter forone of its spokes.

, This invention consists ina rocking lever whose ful crum is beneaththe straw-box, aud which is connected atone end with, and receivesmotion therefrom, a slotted disk fixed upon the same shaft that bearsthe cutter-wheel, and which is combined with two differeut mechanisms,which convert the single motion of the cutter-wheel shaft into twocontrary motions in the feed-rollers.

In the drawing- A is the box wherein the hay to be cut is placed, therebeing at the inner end Iof the box two transverse feed rollers, whereofthe upper (a) is shown'in iig. l, the other being immediately beneaththe upper and at a sufficient interval from it to allow the feed to passbetween the two, these two rollers receiving intermittent rotary motionin opposite directions, a. mode of operation which I am aware is not newby itself, by means of ratchets l) c mounted 011 the roller-shafts atopposite sides of the box A, and pa-wls d e engaging with the ratchets,the former of which pushes while the latter pulls, the pawl d beingjointed to the upper extremity of the bell-crank j', tig. 2, the lowerextremity of which is connect-ed by a link, 7i, with a -lever, li, whichis pivoted between lugs extending downward from the under side of thebox A, and which derives a vert-ical oscillatory motion from a pin, 1.',iixed in one side of a disk, l, at a point in the same noteentral, andwhich passes through a slot, in., in the head of the lever t', whichslot gives thc piu room for lateral motion as itrevolves with the diskl', which. is

i'ixed on the shaft n of thc cutter-whecl o, while 'the rising andfailing of the pin imparts the necessary vibrato'ry movement to thebell-crank f, the pawl c being likewise jointed to the upper extremityof a bell-crank, of, ou the opposite side of the box A from thebell-crank f, the lower end of said heli-crank being connected with theopposite extremity of the same level' t' that operates the otherhe1l-crank, and deriving, from the vertical-vibration of the same, themotion necessary to be communicated to the pulling pawl c.

The pin k may be set nearer the periphery of the disk l than isishown infig. 3, there being a straight series of holes, s, in the disk, any oneof which is litted to receive the pin.

'lhe nea-rer the pin is to the periphery of the disk the longer will beeach intermitted movement of the feed-rollers, and, consequently, thelonger will be the pieces into which the hay is cut. I, therefore, haveameans of regulating the degree of tineness to which I cut my feed. p.

The blade tfornis one of the spokes oi' the ily and cutter-wheel o. Thecurvature. of the blade t is such that its outer endstrikes the hayfirst, and a drawing cut is made toward the center of the wheel, duringrwhich cut the speed of the wheel operates always as the complement ofits power, as the latter increases' from the circumference toward itscenter, while the speed diminishes in the same direction, the speedbeing greatest where the power is least and the power greatest where thespeed is least.

rIhe cutter-wheel is rotated by a familiar arrangement of spur-gearing,shown in 1 and 2.

Ilhe blade t is attached to the cutter-wheel by screws, and may beremoved at any time for sharpening.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is

The lever i, provided at one end with the slot m, and connected at thatend with the disk Y, whichis furnished with a pin, 7.', that passesthrough the slot an, the lever t being connected at dilferentpoints withthe two bell-cranks f o', and combined thereby with the separate pawls dc and ratchets b c, allthese parts being arranged to operatesubstantially as described JOSEPH H. BRADLEY. lwVitnesses:
